I am looking for some information about how to create a custom field type for Joomla 3.7 core custom fields.
Can anyone point me in the direction of a tutorial, an example of anything that may help with the process? I couldn't find official documentation on that.
Please note I am not talking about adding the field to an article, I am talking about creating a new type of field that can be selected from the custom fields component.
I figured it is just a plugin, so I went to copy a core existing one to then expand on that.
However I copied the imagelist, renamed it all to newimagelist, installed all without problem. Created a new field, went into an article, but the newly created field which is just a copy doesn't behave same way. The list dropdown doesn't work. Any ideas?
